| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In the typical unmanned aircraft system (UAS) model, several numbers of unmanned aerial vehicle (UAV) with the velocity of 40 to 100 km/h and the altitude of 150 to 1,000 meters shall be applied to the provision of wide service coverage. Therefore, Doppler shifts are occurred in the carrier frequency by a change in line-of-sight velocity between the UAV and the terrestrial terminal. By observing multiple Doppler shift values for different UAVs, it is possible to detect the position of the user. In order to evaluate the accuracy of the position detection method using multiple UAVs, we have been conducted computer simulations under several types of flight models. From the simulation results and Doppler frequency distributions, it was confirmed that the positioning accuracy depends on the number of UAVs, location of UAVs, and other setting parameters for UAVs. In this study, cosine value of inner product between multiple gradient vectors of the hyperboloid surface at arbitrary point in the evaluation target area is newly presented as the positioning accuracy index in order to express an influence of constellation and initial arrangement of multiple UAVs for position detection accuracy. Further, comparison of simulation results and new proposed evaluation index are conducted by computer simulation and numerical analysis so as to confirm the feasibility of proposed index. |
